PWM Heat

[NightshadowUK]

So okay, Everest is reading my PWM temperature as above 100°C when I dual Prime... is there anything I can do to lower this?

[arthurleung]

Use a fan to blow at your PWM, or drop down your clock speed and voltage

[ultim8um]

Depending on how skilled you are feeling you could always try attaching some mini heatsinks too...

[NightshadowUK]

It was only at 2.4GHz (240 x 10) with 1.4v (stock is 1.35v)...

And as for heatsinks, well:



Abit got there before me.

I read that heatsinks in that area are designed to take advantage of top-down CPU coolers (like all AMD stock ones) but I've got a heatpipe cooler that blows horizontally...

Anyone think investing in a different CPU cooler would help?

Just add a fan which blows at the heatsink. Only cost less than a quid for a cheap 8cm fan.

The PWMIC goes up to 60'C on my DFI board when overclocked and a fan is the only way to get it cooled. Not sure about abit's design but DFI soldered the heatsink on so u breaks the motherboard for taking them off.

I'm using a XP-90 which is blowing top-down already.

[NightshadowUK]

Aye I've just cranked my CPU fan up to max and the PWM temp is still dropping (74ºC now) so I think I may either need to set up a fan (which seems impossible because of the way the case is designed in that area) or get a better CPU cooler...

Any suggestions for a CPU cooler that'll blow over the PWM area as the XP-90 can't be got from Scan?

EDIT: Fan fitting seems to be a no go, the area is just too small --> photo.

THe thermaltake big typhoon dude it is what I used and icould do 250 at 1.35 and use the small V bump in the bios options to give you 1.36ish it is fine on 1.375 up to the 280

[ultim8um]

You could get a fan small enough to fit that area... Helps if u measure it so we know how big it is tho

Bear in mind that a bit of ghetto ducting and a blower would probably drop your temps by loads... Hell even some ducting alone would probably allow you to divert enough airflow from your CPU 'sink to cool that area.

[NightshadowUK]

I tried a piece of plastic running down off the top of the cooler towards the MOSFET in the hope that some of the flow would be diverted but it hardly did anything.

My Dad however has come up with a cunning plan that should allow us to fit an 80mm fan above the area, so when we get that done I'll take some photos.

NOTE: I managed to drop the volts a bit to a BIOS 1.375v ('cause my Opteron is that damn good ) so the PWM gets up to about 80ºC now.

May be the PWMIC is not where you think it is...

[NightshadowUK]

So it's not under those rather fetching aqua heat sinks?

[s29feb]

The are under the two little heatsinks behind the CPU socket infront of the copper fins on the end of the pipe - if my memory serves me right

[GoNz0]

i would have thought you would be better off fixing one of those slot coolers over there ?

if you got the exhaust part down over the heatsinks it would be a perfect solution

[NightshadowUK]

Oh yesh! PWM is 65ºC under full dual prime load, now to crack on with overclocking this baby...

[FatalSaviour]

Nice one Nightshadow Pleased you've got it sorted

[NightshadowUK]

Cheers man , just need to pick up a non-blue LED fan some time, it was the only spare I had!

Might go for the Sharkoon 2000 that CPC rated so highly...
